N. Y., a corporation of Maryland Application July 14, 1944, serial No. 544,839 l Ysoclaims. (o1. s-224) The invention pertains to a railway truck and more particularly to a four wheel type thereof arranged and constructed so as .to be suitable for high speeds.

An object of the invention is the provision, in a railway truck, of a pair of laterally spaced side frames having a vertically movable and spring supported bolster structure maintaining the side frames in constant, spaced relation with laterally and vertically movable journal boxes supporting the ends of the side frames.

Another object of the invention is to provide, in a railway truck, laterally and vertically movable journal boxes so as to present an easy riding railway truck and minimize wear of wheel flanges.

A further object of the invention is to provide, in a railway truck, a wheel and axle assembly capable of independent movement transversely of the truck so that lateral thrusts imparted to the assembly during service will be minimized with regard to the side frames, bolster and car body.

These and numerous other objects of the invention will become apparent from the succeeding description considered together with the accompanying drawings which disclose an exempliiied form of the invention and wherein:

Figure 1 is a partial vertical sectional and partial side elevational view of a portion of a railway truck embodying Ithe present invention.

Figure 2 is a partial plan and partial horizontal sectional view of the railway truck shown in Figure 1. Y Y

tion of the arrows.

Referring now in detail to the drawings wherein there is disclosed-by various gures an arrangement and details of a railway truck em bodying the present invention, and wherein like 40 Figure 5 is a cross sectionalview taken along the lines 5 5 of Figure 1, looking in the direc-` n y 2. truck are counterparts of one another. For the last mentioned reason, therefore, only a quarter of the truck is'shown in the accompanying drawings, it being clearly understood that all four quarters are identical in every respect, and only where it is deemed necessary for a clear and thorough understanding of the exemplified form of the invention will the hereinafter description deviate from the verbal illustration of the portion of the truck disclosed by the drawings. Each side frame comprises the usual top chord or compression member 3 Vand lowerchord or tension member 4 joined intermediate-their ends by longitudinally spaced, vertically extending guide columns 5 to present a bolster or window opening 6 therebetween. Disposed within the window opening and supported by the associated intermediate or horizontal portion 4a of the tension member is a group or nest of resilient means or springs l for yieldingly supporting a superimposed bolster 8 having an extremity 9 mounted upon the spring and also positioned within the window opening. The bolster extremity and related columns have a friction device YI Il associated therewith so as to snub or control the action of the bolster supporting springs. Forming a part of the friction device is Va shoe II cast integrally with and outstanding from the bolster extremity to frictionally engage the columns. This arrangement also maintains the side frames in squared relation so as to keep thefside frames constantly in a predetermined position transversely of the truck and resist the tendency of one side frame of a pair to lead the other side frame. For a more detailed description and illustration of the bolster-side frame connection reference is hereby made to a copending application for Letters Patent of Glenn 1i'. Couch, Serial Number 383,023, led March 12, 1941, for Railwaytruck, and it is deemed suflicient to merely state herein that preferably lthe side frames and bolster are maintained at all times in squared relation with no horizontal angling movement occurring between the side frames and bolster.

The tension member of the side frame beyond the horizontal intermediate portion at the window opening comprises a transverse web I2 terminating in vertical, transversely spaced iianges I3 all of which extend upwardly and outwardly toward an extremity of the side frame. The compression member, alsoy formed channelshaped by a horizontal web I4 and transversely spaced flanges I4a, is directed toward an end of the side frame where. its flanges merge with the flanges of the tension member to continue in having its opposite ends extending around spuds 44 on each cap to maintain the caps and spring in assembled relation. Each spring cap has an outwardly exposed surface 45 which is preferably cylindrical in configuration and bearing against the journal box roof `or compression member web to cradle the resilient means between the side frame and journal Vbox and, so that during a transverse movement of the journal box relative to the side frame, the spring means will rock transversely of the truck to lend itself to service forces. Downstanding from the compression member web and outstanding from the journal box eyelets are spaced retaining means, ears or lugs 46 straddling tongues 41 directed radially of the upper and lower caps and. .by reason of this arrangement, the spring means is maintained in 4a predetermined operable position.V i

Additional resilient means are associated with the journal box to function as yielding supports for the side frame at this location and, since the side frames are locked Atogether by the bolster to prevent a spreading or approaching movement therebetween, the additional `resilient means are so arranged and constructed to facilitate a relatively free journal box transverse movement. As an exemplication of such an arrangement, the upper extremities of the journal box wings adjacent the juncture of the top webs and the inboard side walls thereof are cupped to present longitudinally spaced upwardly facing. or opening bearings 48 in each of which nests a bearing shaft, pivot. means or pin 49. Accordingly, a bearing shaft is horizontally disposed and associated with each journal box wing to have an axis positioned inwardly of the truck from a vertical longitudinal .plane passing through the center of the side frame which, for the sake of clarity, will be hereinafter referred to, as the vertical axis of the side frame. This vertical axis of the side frame is indicated in Figure 3 by a diagrammatical line B-B. Depending from each pivot means is a bolt-like swing hanger or suspension means 50 extending vertically from the shaft downwardly through a related wing. Each suspension means is formed by a stem or arm havingv the upper extremity 52 thereof enlarged and apertured to receive the intersecting pin 49 and for the accommodation of related components projects well below the vertical limits of the journal box. Each swing hanger has an axis indicated by the diagrammatic lineC-C intersecting the vertical axis of the side frame and therefore slopes or is inclined transversely of the truck so that from its upper enlarged extremity it is preferably inclined downwardly and outwardly of the truck.

The swing hanger has its lower extremity 53 threaded externally for` an Vappreciable extent and threaded or rotatably associated therewith.

is a nut-like collark or lower spring seat 54 locked in position by an intersecting cotter key 55 after a predetermined distance between the pivot means and collar has been established. Mounted upon the lower spring seat is a coil or helical spring 56 threaded over the swing hanger stem to be positioned below the overlying wing of the journal box. An upper spring seat 51 intersected by the swing hanger stem and disposed below the related wing, bears upon the helical spring 56 and is arranged to slide along the stem in' response to the actionv of the subjacent 'supporting spring. Both spring seats are provided with ring likeiextensions' 58 which not onlypresent a greater bearing area between the seats and swing hanger but also function as centralizing means for the interposed spring. Disposed above the upper spring seat is a horizontal bearing plate or block 59 also intersected by the swinghanger stem and having a central oblong or elongated aperture 60 ktherein of sufficient extent to afford not only movement of the bearing block vertically or longitudinally of the swing hanger but to v.prevent interference between the bearing plate and suspension means during a pivotal movement of the latter. To retain the upper spring seat and bearing block in a predetermined fixed relation the upper spring seat has upstandving V,therefrom spaced lugs 6| which extend into suitable accommodating downwardly opening reliefs orirecesses B2 in the bearing block with the lugs and reliefs so arranged as to permit a rocking movement of the swing hanger spring means .therebeneath In order to facilitate the hereincontact or point of load application to the swing hanger springs is normally at the intersection of the axis of the swing hanger C-C and the vertical axis of the side frame B-B. This load application is below the horizontal axis of the journal A--A to present a stable arrangement and maintains the load at the center line of the side frame or through the `vertical axis of the side frame. Again, at least in theory, because the side frames are maintained in service in a fixed position transversely of the truck, the swing hanger revolves or pivots midway between its .extremities or about the horizontal line of contact between the bearing plate and upper spring seat or the intersection of the axis C-C andthe axis B B.

YSo as to transmit the load from the side frame Ato the` swing hanger there is provided Aa shelf or ledge SE formed integrally with each jaw side wall adjacent the lower extremity thereof and extending inwardly of the side frame to be mounted or rest upon the bearing block.' Each bearing block has an outer downturned flange 'lpresenting a plane vertical transversely directed surface 68 which is disposed adjacent to a correspondingly arranged inwardly facing surface 69 carried by `a bulged or skirted lower rextremity lll of each jaw end wall. The surfaces `68 and 'B9 may also, during service, contact one another to maintain the journal box within a predetermined location longitudinally of the truck.

From the above it will be noted that various "changes and alterations may be made to the upstanding from said journalbox, tie means asl sociated with said -side'frame and intersecting means@ earned byfsaid swings hangers; andisun# porting sai smoifabiemeansiV 6.2.
